Abstract： Objective To investigate the extracellular matrix （ECM） gene expression profile of saphenous vein （SV） in end-stage renal disease （ESRD） patients undergoing coronary artery bypass grafting （CABG）. Methods Sixty-eight patients who were diagnosed as coronary artery disease by coronary angiography and admitted to Department of Cardiovascular Surgery，Zhongshan Hospital of Fudan University from July 2004 to December 2010 were enrolled in this study. According to whether or not they had preoperative ESRD history，all the 68 patients were divided into 2 groups，the ESRD group with 30 ESRD patients who needed maintenance hemodialysis，and the control group with 38 patients without preoperative renal disease. Preoperative clinical data of all the patients were collected in detail. SV samples were obtained at the time of CABG. Microarray，immunohistochemistry and Western blotting were used to investigate the expression profile of ECM genes of SV in ESRD patients undergoing CABG. Results There was no statistical difference in preoperative clinical variables between the 2 groups except the variables which were directly related to their kidney disease （P＞0.05）. There were 16 genes that were up-regulated at least 3-fold and 3 genes that were down-regulated at least 3-fold in the ECM gene expression profile of SV in the ESRD group patients before CABG. The expressions of matrix metalloproteinases-2 （MMP-2） and matrix metalloproteinases-9 （MMP-9） of the ESRD group were significantly higher than those of the control group （2.60±0.50 vs. 0.70±0.16，1.80±0.40 vs. 0.60±0.15，P＜0.01）. The expressions of tissue inhibitor of metalloproteinase-2 （TIMP-2） and tissue inhibitor of metalloproteinase-3 （TIMP-3） of the ESRD group were significantly lower than those of the control group （0.60±0.19 vs. 2.20±0.30，0.90±0.28 vs. 2.40±0.70，P＜ 0.05）. Conclusion A variety of ESRD-related risk factors of cardiovascular diseases may severely influence on the balance of ECM gene expression of SV before CABG，and the resulting imbalance is a risk factor to aggravate SV graft disease after CABG.

ObjectiveTo explore the practice effect of the combination management of tertiary hospital and community hospital for home peritoneal dialysis patients. MethodsA total of 50 patients of end-stage renal disease from December 2012 to May 2013 were involved in this study, including 26 males, and 24 females with the average age of 47.1±13.9. The patients were randomly divided into hospital group (30 patients) and combination group (20 patients). For the patients in the hospital group, the specialists take care of them with regular outpatient service and follow-up; for the patients in the combination group, they were taken care by doctors from both tertiary hospital and community hospital, while the community general practitioners were trained by the tertiary hospital regularly with peritoneal dialysis basic treatment and standardization management and communication. All the patients were managed for 9 months. ResultsAt the end of the observation,the dialysis adequacy success rate, hemoglobin, blood potassium, phosphorus, calcium, albumin, CO2CP, blood pressure success rate, the incidence of peritonitis, and average monthly medical treatment expense between the two groups were not statistically different (P>0.05); the difference in cost of transportation was statistically significant (P<0.05). ConclusionThe standardization manage of combination of tertiary hospital and community for patients with home peritoneal dialysis may reduces the patients' expense in transportation, and improve the community general practitioners' level of basic knowledge and indication of peritoneal dialysis.
ObjectiveTo explore the safety and efficacy of patients with dialysis-dependent end-stage renal disease who underwent coronary artery bypass grafting (CABG). Methods We retrospectively analyzed the data of 40 dialysis-dependent patients who underwent CABG in Beijing Anzhen Hospital between January 1, 2006 and August 20, 2013. There were 27 male and 13 female patients at mean age of 63.52±9.17 years. Of them, 33 patients underwent off-pump CABG were in the off-pump CABG group, while 7 patients underwent on-pump CABG were in the on-pump CABG group. ResultsThe average number of the grafts is 2.27±0.68. In the off-pump CABG group, 1 patient died from perioperative myocardial infarction with mortality of 3.0%.In the on-pump CABG group, the operative mortality was 28.6%, with 1 death because of serious infection and secondary multi-organ failure 15 days after the operation, and another death because of ventricular fibrillation 4 days after the operation. The follow-up rate was 100.00%. Overall mean follow-up time was 4.3±2.1 years. During the follow-up, the overall survival rate at 1 year, 3 years, and 5 years was 92.68%, 89.43%, and 82.04% respectively. ConclusionCABG can be performed in the patients with dialysis-dependent end-stage renal disease who also suffered with severe coronary artery disease, despite higher mortality. Surgeons should carefully select patients for the operation. Through optimal way of revascularization, and reasonable perioperative therapy, especially more actively use of continues renal replacement therapy, good results could be got in those kinds of patients.
Objective To evaluate the safety and efficacy of total hip arthroplasty (THA) in patients with end stage renal disease (ESRD). Methods Between December 2009 and May 2016, 30 THAs were performed in 28 patients with dialysis-dependent renal failure (18 patients) or renal transplantation (10 patients). A retrospective case control study was carried out to compare these 28 ESRD patients (ESRD group) with a matched cohort of 28 nonrenal patients (control group). There was no significant difference in gender, age, hip side, American Society of Anesthesiology (ASA) classification, comorbidities, and preoperative Harris score and hemoglobin (Hb) level between 2 groups (P>0.05). The complications during hospitalization, Hb level changes, perioperative transfusion rate, hospital stay, and hospitalization costs in 2 groups were evaluated; and the creatinine changes of dialysis patients in ESRD group were evaluated. During the follow-up period, 90 days readmissions, periprosthetic infection, prosthesis loosening, hip Harris score, and deaths were recorded. Results There was no loss of follow-up. The mean postoperative follow-up of ESRD group was 3.4 years (range, 1.0-7.4 years) and control group was 3.5 years (range, 1.0-7.4 years). Differences in hospital stay and the drop of Hb was not significant between 2 groups (P>0.05). The hospitalization costs and perioperative transfusion rate were significantly higher in ESRD group than in control group (P<0.05). There was no significant difference in creatinine value of dialysis patients in ESRD group between pre- and post-operation (t=1.804, P=0.089). At last follow-up, the Harris score was significantly higher than preoperative score in both groups (P<0.05); however, there was no significant difference in Harris score between groups (t=1.278, P=0.207). In ESRD group, 5 patients presented complications, 1 patient was readmitted to hospital, and 2 patients died during the follow-up. In control group, 1 patient presented complications, and there was no 90 days readmission and no death. During the follow-up period, there was no loosening or revision in 2 groups and the prosthesis was in good position. Conclusion THA can improve joint function and life quality of ESRD patients, but the risks of operation, perioperative complications, transfusion rate, and cost are high. Correct perioperative evaluation and management can help ESRD patients safely go through the perioperative period.
Sarcopenia has the characteristics of high morbidity and mortality, which seriously affects the quality of life of patients. Continuity of care, as an emerging nursing model in recent years, aims to improve self-care abilities of patients and their families, which can effectively reduce the rate of rehospitalization, and improve the quality of life of patients. This article starts with psychological intervention, nutrition guidance, patient exercise and medication guidance, and explores the application of continuity of care in patients with end-stage renal disease complicated with sarcopenia, analyzes the application of continuity of care in patients with end-stage renal diseases, and describes the implementation content and form of continuity of care, aiming to help its further promotion in clinic.
Kidney transplantation is an ideal treatment for patients with end-stage renal disease. Circulating alloantibodies against donor human leukocyte antigens and blood group antigens can impair allografts, shorten allograft survival, and limit access to kidney transplantation. Furthermore, the presence of donor specific antibodies is associated with increased incidence of antibody-mediated rejection and decreased graft survival following transplantation. Plasmapheresis, an extracorporeal therapy directed at removing plasma proteins that has been found to minimize the effects of perioperative sensitization in kidney transplantation. Plasmapheresis enables transplantation across the barrier of ABO blood group incompatibility. In addition, it is also an important approach for the treatment of antibody-mediated rejection. Therefore, studying the application of plasmapheresis in perioperative period of kidney transplantation is expected to increase the chance of transplantation and improve the outcomes following transplantation. This article introduces the application of plasmapheresis in the perioperative period of kidney transplantation.
Objective To analyze the human leukocyte antigen (HLA) gene polymorphism and haplotype frequency and distribution in Han patients with end stage renal disease (ESRD) in Sichuan province, and explore the correlation of HLA gene polymorphism and haplotype with the susceptibility to ESRD in Sichuan Han patients. Methods Polymerase chain reaction-sequence specific oligonucleotide probe hybridization typing technique was used to detect the HLA-A, -B, -DRB1, and -DQB1 genotypes of Han patients with ESRD and healthy participants. The allele and haplotype frequencies in the ESRD group and the control group were analyzed using SPSS 25.0 and Arlequin 3.5.2.2 softwares. Results A total of 756 ESRD patients and 1118 healthy participants were enrolled. In the four loci of HLA-A, -B, -DRB1, and -DQB1, the frequency of HLA-B*39 allele in the ESRD group was higher than that in the control group [3.37% vs. 2.19%; χ2=4.850, P=0.028, odds ratio (OR)=1.558, 95% confidence interval (CI) (1.047, 2.319)], the frequency of HLA-DQB1*06 allele in the ESRD group was lower than that in the control group [17.39% vs. 21.20%; χ2=8.264, P=0.004, OR=0.783, 95%CI (0.662, 0.925)], and the frequency of HLA-DQB1*04 allele in the ESRD group was higher than that in the control group [7.41% vs. 5.46%; χ2=5.867, P=0.015, OR=1.386, 95%CI (1.063, 1.807)]. The frequencies of 10 haplotypes, including HLA-A*11-B*39, HLA-DRB1*15-DQB1*06, and HLA-DRB1*04-DQB1*04, were significantly different between the ESRD group and the control group (P<0.05), among which 9 haplotypes were possibly susceptible to ESRD and 1 haplotype was possibly protective. Conclusions HLA gene polymorphism is closely related to the susceptibility to ESRD. HLA-B*39 and HLA-DQB1*04 may be susceptible genes for ESRD in Sichuan Han patients, while HLA-DQB1*06 may be a protective gene. In addition, 10 HLA haplotypes are possibly associated with the susceptibility to ESRD in Sichuan Han patients.
Patients with atrial fibrillation complicated with kidney disease have a high risk of stroke and bleeding, and have some limitations or contraindications to oral anticoagulants. Left atrial appendage closure has been used as an alternative to oral anticoagulation in patients with atrial fibrillation, but its efficacy and safety in patients with atrial fibrillation and chronic kidney disease need to be further confirmed. This paper intends to review the research progress of left atrial appendage occlusion in patients with atrial fibrillation complicated with chronic renal insufficiency.
